5Claims.

This invention relates to improvements in double glazed Window sashes in which the edges of the inner and outer glazing panels are mounted in grooves Vformed in a resilently compressible glazing strip which is Acompressed between inner and `outer sections of a sectional vsash frame to provide pressure contact between the glazing panels and the side walls of the glaz- 'ing strip grooves in which the panels are mounted.

One object of the present invention is to provide an improved double glazed window sash .of .the character described in which the sections yof the sash frame are designed and .secured together in Va novel manner which improves the pressure ,contact between `the glazing panels and the ,side Walls `of* the glazing Strip grooves in which the edges of the panels are mounted.

Another object of the invention is to provide .a vdouble glazed sash of the character described in which the sections of the sash frame are de- .tachablly secured together in a manner ,which improves the insulating eiciency of the sash assembly.

Another object of the invention is to provide a `double glazed Asash of the character vdescribed in which the sections of the sash are detachably secured together .by coupling dowels which are easily and quickly applied and removed.

Other objects, advantages and characteristic features o f the invention will be more .readily understood from the following .detailed description of the preferred embodiment shown in the accompanying drawings, -in which- 'Fig. 1 is an elevational view Y0f a double glazed sash assembly designed in accordance with my invention.

Fig. 2 is a fragmentary vertical sectional view taken substantially v.along the .Section Iline k2,-2 o f'Fig. 1.v

Fig. 3 is a fragmentary vertical sectional View of a frame section constituting vonce-half of the sash frame shown in Fig. 2.

Fig. 4 is a view similar to Fig. 3 but showing the frame section constituting the lremaining 'half ofthe, complete frame assembly shown in Fig.2.

Fig. v5 is a sectional view o f one'of the dowels employed for securing the sash frame sections together in their assembled rela-tion.

`As shown in the drawings, my improved sash assembly comprises a pair of laterally spaced ,glazing panels 5 having their edges mounted in ,grooves 6 `formed Yin a glazing strip J made of .rubber .Qrother -reslently compress'ble materiaL `fIhe glazing strip I is confined under compres- `each ltrarne member of section 9 has one limb I-2 disposed in a plane paralleling the glazing panels 5. This limb I2I comprises a relatively thin inner portion I3 and a relatively thick outer portion I4. The relatively thin innerl portion I 3 constitutes one side wall of the glazing channel 8. inwardly beyond the thin portion I3 to provide a ledge ,i5 which forms the minor portion of the width of the bottom wall of glazing channel A8. A strip I5, lof resilient Ymaterial such as rubber, is fitted in a groove I1 formed in the vthicker portion I4 of limb I2 adjacent the ledge I5. The remaining limb I8 of each frame member of sash section ,9 extends inwardly across the adjacent outer edge of glazing strip 'I in .spaced relation thereto. This limb I8 is provided with a lengthwise extending groove I9 which is serrated to provide longitudinally extending V-shaped ribs 23. Each limb I8 is also provided, adjacent its opposite ends, with drilled dowel-receiving openings 2 I.

The sash frame section I0 is also substantially rectangular in outline and is composed of substantially T-shaped frame members secured together in end to vend relation. Each T-.shaped frame member Aof sash frame tsection I0 is arranged with its head portion 23 lying in the plane paralleling the glazing panels 5 and its stem portion 24 extending inwardly over the adjacent edges of the glazing panels so that its surface 25 formsv the major portion of the widthof the bottom rwall of glazing channel 8. Each stem portion 24 terminates in a V-shaped rib 2 6 which bears against the previously mentioned strip .of resilient material seated in the groove I1 of the opposing frame member of frame section :9. The lste-m portion 24 of each T-shaped side member of sash section IB is provided with .an outwardly facing groove 2l .opposing but spaced from .the inwardly facing ,groove I9 formed in the limb I8 of the corresponding ,L-shaped frame member of sash frame section S. This groove 2,1 -is shaped to provide longitudinally extending Vshaped ribs 21a. That portion of the head `23 ,of .each T- shaped ,frame member of frame section v.Ill .which .extends inwardly irom stem portion .2.;4 .forms the The relatively thick portion I 4 projects remaining side wall of glazing channel 8. The remaining part of said head 23 which extends outwardly from said stem portion is formed with a groove 28 containing a strip 29 of resiliently compressible material which is engaged by a V- shaped rib 30 formed on the inner edge o f the limb I8 of the opposing L-shaped frame member of sash frame section 9.

The component parts of the sash described herein are assembled in the following manner: The glazing strip 'I having the glazing panels 5 mounted therein is arranged between the complementary half sections 9 and l0 of the sash frame as shown in Fig. 2. The initial width of the glazing strip 1 is such that when frame sections 9 and I0 are fitted against opposite sides thereof, the grooves I9 of the frame members of frame section 9 will be slightly offset outwardly with respect to the opposing grooves 21 of the frame member of fra-me section I0. Suitable clamps (not shown) are applied to frame sections 9 and I to force them together to compress the interposed glazing strip 1 and to align the grooves I9 of frame section 9 with the opposing grooves 2l of frame section lll. Then, while the clamps are still in place, four locking dowels 32 are inserted'through the dowel-receiving openings 2l of frame section 9 so that each dowel is fitted in the grooves I9 and 2l of opposing frame members of frame sections 9 and I0. 'I he V-shaped ribs of grooves I9 and 2l decrease the area of frictional contact between the sash4 frame sections and the dowels 32 so as to enable the latter to `be -more easily slid into and out of said grooves.

Each dowel is a suiiciently tight t in the grooves in which it is inserted to hold the sash frame sections in their glazing strip compressing relationV when the clamps previously referred to are removed. In this relation of the sash frame sections the resiliently compressible strips IS and 29 are compressed by the engaging V-shaped ribs 23 and 30. The dowels 32 inserted between the opposing frame members at the top and bottom of the sash frame shown in Fig. l are dimensioned and arranged so that in their nal position they lie between the drilled openings 2l through which the remaining dowels are inserted between the opposing sash frame members at the sides of the sash frame.

The dowels 32 may be of solid or hollow construction and may be formed of metal, plastic, or any other suitable material. As shown in Figs. 2 and 5, each dowel is preferably provided with a fabric covering 32a having a nap 32h.

Having thus described the nature of my invention and a preferred embodiment thereof, it will be understood that various modifications may be resorted to within the scope and spirit of the invention as defined by the appended claims.
